DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

In the present application, a backpack 100 comprises a backpack body 101 and a back cover 102 mounted on the backpack body 101 detachably.

Specifically, an accommodating house is formed in the backpack body 101, and the accommodating house is configured for loading goods, such as books, clothes, and other things. A first opening is defined in the backpack body 101 to communicate the accommodating house with outside. The back cover 102 is connected with the backpack body 101 to form the backpack 100, and the back cover 102 can be moved to cover or open the first opening of the backpack body 101. Thus, the backpack 100 can be used as a conventional backpack.

Advantageously, in the present application, two straps 103 are arranged on the back cover 102. Specifically, the two straps 103 are sewed on the back cover 102. Of course, the connection method between the straps 103 and the back cover 102 is not limited to the sewed method, and can be a buckled method. Particularly, two ends of each of the straps 103 are buckled on the back cover 102 to achieve a connection between each of the straps 103 and the back cover 102. Thus, when the back cover 102 is mounted on the backpack body 101 to form the backpack 100, a user can carry the backpack 100 conveniently via the two straps 103. It is understood that there can also be only one strap 103 sewed on the back cover 102.

Normally, the two straps 103 are flexible, and can be made of cotton or chemical fiber, etc.

Additionally, the two straps 103 can also be arranged on the backpack body 101. Advantageously, the two straps 103 are respectively sewed on two external side surfaces of the backpack body 101 that are opposite to each other. Moreover, both the two straps 103 abut the first opening of the backpack body 101. Thus, when the back cover 102 is mounted on the backpack body 101 to form the backpack 100, a user can carry the backpack 100 via the two straps 103 conveniently.

Of course, the two straps 103 can also be mounted in the accommodating house. In this situation, two through-holes corresponding to the two straps 103 should be defined in the back cover 102. When the back cover 102 is mounted on the backpack body 101, the two straps 103 can pass through the two through-holes of the back cover 102 respectively, so that a user can use the two straps 103 to carry the backpack 100.

The present application provides three connection methods for connecting the back cover 102 with the backpack body 101, and the three connection methods are respectively described in the following three embodiments.

FIG. 1 is an exploded view of a backpack 100 of a first embodiment of the present application.

In the first embodiment, the back cover 102 is mounted on the backpack body 101 via a zipper 200 detachably. Specifically, the zipper 200 includes a first zipper rack 201 and a second zipper rack 202 corresponding to the first zipper rack 201. The first zipper rack 201 is disposed along the edge of the first opening of the backpack body 101, and the second zipper rack 202 is disposed on the back cover 102. A zipper puller 203 is movably mounted on the first zipper rack 201 or the second zipper rack 202. Thus, the first zipper rack 201 can engage with the second zipper rack 202 via the zipper puller 203, so that the backpack body 101 can be mounted on the back cover 102.

It is understood that two zipper pullers 203 can be provided. In this embodiment, one zipper puller 203 is movably mounted on the first zipper rack 201, and the other zipper puller 203 is movably mounted on the second zipper rack 202. The first zipper rack 201 can engage with the second zipper rack 202 via any one of the two zipper pullers 203, so that the backpack body 101 can be mounted on the back cover 102. Moreover, the first zipper rack 201 can be separated from the second zipper rack 202, so that the backpack body 101 can be separated from the back cover 102. By adopting the two zipper pullers 203, the situation that the only one damaged zipper puller 203 causes unavailability of the backpack 100 is avoided.

When the backpack body 101 is mounted on the back cover 102, the zipper 200 can be used to open or close the first opening of the accommodating house. Thus, goods can be received by the accommodating house.

Of course, a second opening can be defined in the backpack body 101 to communicate the accommodating house with outside. Moreover, the second opening can be sealed by a sealed device 500 mounted on the backpack body 101, such as a zipper, a buckle or a Velcro, etc. Thus, goods can be put into the accommodating house through the second opening.

FIG. 2 is an exploded view of a backpack 100 a of a second embodiment of the present application.

The backpack 100 a also includes a backpack body 101 and a back cover 102. The difference between the backpack 100 a of the second embodiment and the backpack 100 of the first embodiment is that the backpack 100 a of the second embodiment adopts another connection method for connecting the backpack body 101 with the back cover 102.

In the second embodiment, the back cover 102 is mounted on the backpack body 101 via a plurality of fasteners 300 detachably. Specifically, each of the fasteners 300 includes a fastener body 301 and a recess 302 corresponding to the fastener body 301. A plurality of the fastener bodies 301 are disposed along the edge of the first opening of the backpack body 101, and a plurality of the recesses 302 are disposed on the back cover 102. Thus, as the fastener bodies 301 are detachably buckled in the recesses 302 respectively, the backpack body 101 is mounted on the back cover 102.

It is understood that a plurality of the recesses 302 are disposed along the edge of the first opening of the backpack body 101, and a plurality of the fastener bodies 301 are disposed on the back cover 102, as shown in FIG. 2.

The fastener body 301 can be separated from the recess 302 corresponding to the fastener body 301, so that the first opening is open. Goods can be put into the accommodating house via the first opening.

FIG. 3 is an exploded view of a backpack 100 b of a third embodiment of the present application.

The backpack 100 b also includes a backpack body 101 and a back cover 102. The difference between the backpack 100 b of the third embodiment and the backpack 100 of the first embodiment is that the backpack 100 b of the third embodiment adopts another connection method for connecting the backpack body 101 with the back cover 102.

In the third embodiment, the back cover 102 is mounted on the backpack body 101 via a Velcro 400 detachably. Specifically, the Velcro 400 includes a velour area 401 and a crochet area 402 corresponding to the velour area 401. The velour area 401 is disposed along the edge of the first opening of the backpack body 101, and the crochet area 402 is disposed on the back cover 102. The crochet area 402 is stick to the velour area 401 detachably. Thus, as the crochet area 402 is stick to the velour area 401, the backpack body 101 is mounted on the back cover 102.

It is understood that the crochet area 402 can be disposed along the edge of the first opening of the backpack body 101, and the velour area 401 can be disposed on the back cover 102 correspondingly.

The velour area 401 can be separated from the crochet area 402 corresponding to the velour area 401 partially, so that the first opening is open. Goods can be put into the accommodating house via the first opening.

Advantageously, the backpack body 101 can be mounted on the back cover 102 by adopting both the zipper 200 and the fastener 300, wherein the fastener 300 has a locating function for the convenience of closing the first opening via the zipper 200.

Additionally, the backpack body 101 can also be mounted on the back cover 102 by adopting both the zipper 200 and the Velcro 400.
